.To all whom, t may concern:

Be it known that I, -LoUIs JOSEPH ANTON STANIEWICZ, bookbinder, of thelcity of Chat# ham, in the county of Kent, in the Province of Ontario,Canada, have invented certain new and useful Improvements inBookbi'nders Clamps, as hereinafter more particularly explained. l

My invention relates to improvements in adjustable clamps orclamp-stands for holding books during embossing and gilding, 85e.; andthe object of the invention is to devise a simple clamp-stand whereby abook maybe tilted or swung horizontallyinto a convenient position forthe workman to emboss, gild, or otherwise decorate or work upon it; andit consists, essentially, of a stationary base arcshaped incross-section, a rocking base also arc-shaped in cross-section vanddesigned to rockvupon the stationary base, such stationary base beingdesigned to'be changed in position or swung horizontally and heldstation: ary while in use and the rocking base being provided withclamping-bars between which the bookis held,the clamping-bars and clampsbeing suitably secured to the top of the rocking base and such rockingbase being provided with a central spring connection to the floor andthe parts being otherwise arranged and constructed in accordance with myinvention. p

Figure l isa perspective view of my clamping-stand, showing it placed ona table and exemplifying the applicability of my invention. Fig.,2 is across-section. detail of the base-board. yFiga isan inverted detail ofthe stationary baseor base normally held stationary. Fig. 5v is a detailof" the rocking base. Fig. 6 isa detail of the ball-bearing throughwhich the flexible cord extends which connects the rocking base toV thestationary base. Fig. 7 is a detail of the tension-spring for theflexible cord and the device for varying the tension of the same.

In the drawings like letters of reference indicate corresponding partsin each gnrel..

Al isa table of any ordinary construction, upon which my device isplaced. i B is the base, which is provided with a central ring b, heldin a circular opening in the same and in the center of which is a holeb.

C is the base, which is ordinarily held sta-I Fig. 3 is ai Yplaceduppermost.

hole b2 in the base B into a hole c in the base.

The plunger D is provided with an annular projection d, between whichand the enlarged hole through which the plunger extends fits the spiral.spring d in order to hold the plunger in the hole c in thebase C.

It will be noticed that the stationary base O is arc-shaped incross-section and provided with end grooves c?, provided lwith rubberstrips, as indicated.

E is the rocking base, which is provided with a central hole e, a crossdovetail-shaped groove e', in the center of which is located theball-bearing e2, comprising the rings e3 and `e4 and balls e5 and beadse, provided with suitable rubberstrips e7, designed to enter thecorresponding grooves in the stationary base C.

F is a cord which extends through the holes e, being suitably knotted atthe top above the ball-bearing e2, the holes c and b to the spiralspring G, which is connected at the top to the triangle g, as indicated.

g is a bracket provided with a depending hook g2, and g3 is athumb-screw which extends through the upper `member of the bracket andthe basepof the triangle.

By means of the thumb-screw g3 the tension of the spring G maybevaried-that is -to say, the tightness by which the rocking base E isheld upon the stationary base O may also consequently be varied. n

H H are clamping-bars, between which the book I Vis held, the back ofthe book being The bars H and H are provided with tongues 7L and h',which fit into the groove e' and are designed to have longitudinalmovement therein. J isa clamping-screw which extends through Vthe bars Hand Hl and the tongue 7L against the base' of the groove e', thisclamping-screw being designed to hold the clamping-bars in position whenplaced centrally crosswise of the rocking base E.

K represents ordinary clamping-screws, which extend through the endpieces k2, at-

tached to or forming part of the clampingbars H.

IOO

By loosening the clamping-screws the book may be removed. Such screwsare preferably provided with right and left hand threads meeting at thecenter, so that by turning the screws the bars move apart in order thatthe book may be quickly released.

Having now described the principal parts involvedin my invention, Ihavebriefly to state and it will be readily seen that the book may be tiltedover laterally into a position convenient for the workman, so that hecan emboss and burnish without any strain and with a perfect rest forhimself upon the book or part of the frame. work requires release theplunger D and turn the whole device around horizontally to any desiredposition and work on it in that position either at right angles orotherwise to the position shown in the drawings.

The spring G and cord F, it will be readily seen, allow of the base E torock upon the base C with facility, and yet connect them securelytogether. Should it be desired to hold the bases G and E stationary, Iprovide end bolts or pins L, which fit into brackets Zand Z. on thebases C and E, respectively. The bolts or pins L are of course withdrawnshould it be desired to allow the bases to rock one upon the other, soas to tilt the book into any convenient position desired.

That I claim as my invention isl. The combination with the stationarybase provided with a curved or arc-shaped top, of the rocking baseprovided with a curved or are-shaped bottom designed to rest upon thearc-shaped top, the clamping-bars secured on the rocking base anddesigned to receive between them the book to be embossed, means forholding such bars together to grip the book and means for connecting thebases together, so as to permit of a rocking lateral movement as and forthe purpose specified.

E3. 'lhe combination with the stationary base provided with a curvedorare-shaped top, of the rocking base provided with a curved orarc-shaped bottom designed to rest upon the arc-shaped top, theclampingbars secured on the rocking base and designed to receive betweenthem the book to be embossed, the handscrew extending through the endsof the bars and means for connecting the bases together, so as to permitof a rocking lateral movement as and for the purpose specified.

3. The combination with the stationary base provided with a curved orarc-shaped top, of the rocking base provided with a curved or arc-shapedbottom designed to rest upon the arc-shaped top, the clamping-barssecured on the rocking base and designed to receive between them thebook to be embossed,the hand- IIe also may, if desired, where the fscrew extending through the ends of the bars, the said rocking bar beingprovided with a cross-groove, ahand-screw extending through theclamping-bar into and against the bottom of such groove and means forconnecting the bases together so as to permit of a rocking lateralmovement as and for the purpose specified.
